Hey
So here is my experience with panels and smm and all of that.
I did it for the longest time and I even had a marketplace thread opened. You can check it out if you dig deeper.
At the beginning, you have to purchase a template ( and thats why they all look similar)
You pay a monthly fee of $30-$60
There are two very big sellers of scripts and thats what everyone uses.
Then, you have to create services and connect them to someone else's panel ( they make it so easy for you to do that)
Now let me explain something that not everyone understands, 99.99% of the panels you find are resellers and are doing exactly what I said above. That's what I was doing.
Now I was selling 1,000 instagram likes for 0.1$ and buying it for $0.03
Someone would order 1,000 instagram likes only and then complain that they only got 600... I made off this order around $0.07 ( literally 7 cents), and I am not the supplier of the service, so I will have to ask whoever is supplying me the likes for an explanation( he probably is a reseller too and will take 3 days to answer me cause he wants to ask his guy) and you're doing this for 7 cents.
Now don't get me wrong. I chose to do this, and was sooooo pumped at the beginning and wanted to kill it and make so much money. Which I did the first 20-25 days. Then I started getting lots of clients... and then lots of problems... Up until I just stopped answering and some people are SOO annoying and trust me customer support is the hardest thing ever.. So yea.. I had a shitlist opened for the business or something.. Paid everyone back and deleted the domain cause I was like fuck this shit..
Best panels that I would recommend ( They had best customer support and have been doing this for a while):
http://ksaebuy.com I know the owner personally and he is doing this full time and has been doing it for a while. Resells some products but also supplies others
http://justanotherpanel.com/ Huge panel and he has people hired just for customer support
